Can confirm; it's already been pulled.
Just another sign of how ludicrous these carriers are for charging MORE MONEY to use the SAME CONNECTION on another device. US Telecom is awful.
Customers who use tethering will on average use more data per month than customers who don't use tethering, and therefore are more expensive.
You have a contract that gives you a certain amount of data per month. The carrier figures out how much data people on that contract use ever month on average, and that determines what these people cost the carrier per month, and then they add some profit margin, and that is what you are charged. If people who use tethering are added to the mix, then the average cost to the carrier, and therefore the average monthly charge go up for everybody. The way it works now, only people using tethering pay for the extra cost, and everybody who doesn't use tethering is quite happy with that.
I honestly think there should be a lawsuit against AT&T and there data/tether plans. I find it quite ridiculous that your paying $25 for 2GB of data and you can't choose the way you want to use that 2GB. You have to purchase a tether plan for an additional $20 to include 4GB of data? What about the users who use less then 2GB even with tether?
You don't pay for 2GB of data. You pay for the average amount of data that all the customers on the "up to 2GB, no tethering" plan are using, which is a lot less than 2GB. If AT&T sold an "up to 2GB with tethering" plan, then you would pay for the average amount of data that all the customers on the "up to 2GB with tethering" plan are using, which would be more data and therefore more expensive.
This is actually a valid point. You can easily dispute the chargers with whatever carrier you are on just by saying you thought it was OK because it was in the app store, so you were under the impression that if apple allows it, you thought the carrier allowed it too.
There's a problem with that. AT&T will not say "oh, you were naughty, now we charge you for tethering". AT&T will say "we notice you are tethering, so we put you on to the appropriate plan unless you stop doing it". So the carrier told you that it wasn't allowed, and they will probably be able to claim that any future tethering means you agree being put on the tethering plan. At that point you can't claim anymore that you thought it was allowed. For charges for past tethering you may be right, but they are not doing that.
